Problems solved by technology
As a clean new energy source, solar energy can be used as a renewable energy source for dehumidification runners without generating waste residue, waste water, and waste gas. However, solar energy has a low energy density and is greatly affected by the weather, so it must be based on energy conservation and environmental protection to overcome these shortcomings

The invention discloses a hybrid air conditioning system for combining a hybrid gas heat pump system, solar energy and dehumidification. The novel hybrid air conditioning system mainly comprises a hybrid driving system, a heat pump system, an afterheat recovery system, a solar heat collecting system and a dehumidification system. The system uses the hybrid gas heat pump system based on a CVT as a power core of the whole air conditioning system; and the CVT can continuously adjust the speed ratio, so that an engine is always operated in an economical area, and the whole heat pump system is always operated under the optimal working condition. A solar heat collector collects heat, and the afterheat recovery system recovers low-grade energy of a cylinder jacket and smoke of the engine, so that the air return temperature rises to the regeneration temperature, and is reduced, or even additional energy has no need to be provided by the external. The afterheat recovery system adopts a bypass heat recovery mode, so that the temperature of the engine can be kept in a safe and effective range, and living hot water is supplied.
Description
technical field [0001] The invention relates to a novel composite air-conditioning system, in particular to a composite air-conditioning system which combines waste heat recovered by a hybrid drive system and solar heat collection for dehumidification. Background technique [0002] Since natural gas has no SO in the combustion process 2 emissions, CO 2 The emission of natural gas is also much smaller than that of coal, so natural gas has great development prospects as a low-carbon energy source among fossil energy sources. In a gas heat pump system, natural gas is the energy source and the compressor is driven by the gas engine. However, when the external cooling and heating load fluctuates, the gas engine will deviate from its economic zone, resulting in a decrease in engine thermal efficiency, an increase in fuel consumption and emissions, which will affect the stability of the engine and the performance of the entire system. The hybrid gas heat pump system uses hybrid t...
